At
the far end of the dungeon, an over sized keyring bearing any number
of keys, hangs from a hook by a stone archway. Raven hurries toward
over, snatching it off. As he does, an arm seems to grow out of the
arch, grabbing his wrist. A second arm appears and Raven realises
that the arch itself is coming to life. It plucks the keyring from
Ravens hand and returns it to the hook. The arch twists slightly and
its legs emerge, before it turns toward him with a leering stone
grin. It grabs Raven's other arm and lifts him clear off the ground.
“Oh
no,” says the guide, “Trolls.”
